IMPROVEMENT IN MACHINES FOR MAKING STOVE-PIPES, MOLDINGS, CONDUC'I'ORS,EAVES-TROUGHS, &C.

Specification forming part of Letters Patent No. 1,755, dated epteinbcr2, 1.840.

To all whom t may concern,.-

Be it known that I, JOHN FARRAR, of Cuyahoga Falls, Summit county, andState of Ohio, have invented a new and Improved Method of MakingMoldings, Conductors,

` Eaves-Troughs, Stove-Pipes, ctc. by the application of a roller andcylinder; and I do hereby declare that the following is a full and exactdescription.

The nature of my invention consists in applying a roller and cylinder tothe forming of moldings, conductors, eaves-troughs, stovepipes, &c.

To enable others skilled in the art to make and use iny invention, Iwill proceed to describe its construction and operation.

The machine consists of a bed-piece, Plate l, Figure l, for tin work,twenty inches long, eight inches wide, two inches thick, which is to bemade fast to a common work-bench by means of a bolt. 2 2, Fig. 1, arepieces of one inch or more thick, and siX` inches wide, eight v incheslong, with holes through them, and fastened to the bed-piece by screwsthe size oi' the roller orv mandrel 4, Fig. 1, which has af groove cutin its face along its length, to catch the edge of the tin to be worked.

3, Fig. l, is a concave bed, made of wood or iron, to lit the size oftheroller desired for dftierent kinds of pipe; 5, the crank; 6, the screwon the end of roller for crank 5 2Fig. 2,

`cross-section of concave bed; 3, cross-section of roller; 4, groove inroller. The roller is made to pass through the pieces 2 2, Fig. l, andis drawn out after the formation. of each piece, the end of the tube orpipe worked striking against the pin 2, which will keep it in its placewhile the roller is drawn out, and the piece worked is taken away andthe roller slid back, ready to work another piece, Sie.

Vhat I claim as vmy invention, and desire to secure by Letters Patent,is-

The employment of a roller or cylinder with a groove, in combinationwith a concave bed for making moldings, conductors, eavestroughs,stove-pipes, &c., as herein described.

JOHN FARRAR.
